SPECIFICATION forming part of Letters Patent No, 719,354, dated January27, 1903.

Application filed .Tune 25, 1902. Serial No. 113,154. (No model.)

T0 (0 whom it may concern:

Be it known that I, HERMAN MOON, a citizen of the United States,residing at Grove City, in the county of Mercer and State ofPennsylvania, have invented a new and useful Reversing-Gear, of whichthe following is a specification.

This invention relates to an improved reversing-gear for amotion-transmitting mechanism.

The object of the invention is to provide a reversing-gear by means ofwhich a driven member may be driven either with or reversely withreference to the driving member and may be permitted to rotateindependen tly thereof or to remain idle while the driving member is inrotation; and the invention consists in the peculiar construction andcombination of devices hereinafter fully set forth and claimed.

Figure 1 of the accompanying drawings represents a longitudinal verticalsection of a reversing-gear embodying these improvements, showingvthemechanism thereof so adjusted that the driven member will be rotated inthe reverse direction from the driving member. Fig. 2 represents apartial side elevation thereof so adjusted that the driving and drivenmembers will rotate in the same direction. Fig. 3 represents atransverse sectional view thereof on two planes indicated by the dottedline a: cc of Fig. 1. Fig. 4 represents a similar view taken on line y yof Fig. 1. Fig. 5 represents a similar view taken on line .2 of Fig. 1.Fig. 6 represents a similar view taken on line 6 6 of Fig. 1. Fig. 7represents a sectional view taken on line 7 7 of Fig. 1, showing thehead of the motion-transmitting member and the clutchhead disposedtherein in elevation and the other parts of the gear at the rearthereof. Fig. 8 represents a transverse section taken on line 8 8'ofFig. 1. Fig. 9 represents enlarged detail views of the clutch members inposition ready to be assembled.

The same reference-numerals indicate corresponding parts in all thefigures.

The shaft 1 will be assumed for the purposes of this specification to bethe driving member and to be continuously in rotation. The

pulley 2 will be assumed to be the driven member, to which motion iscommunicated from the driving member by means of a motion-transmittingmember, hereinafter to be described.

On the shaft 1 is keyed a sleeve 3, which has a circular flange 4 atoneend thereof, which will be called the inner end. A sleeve 5 is loose onthe sleeve 3 and is provided at the end opposite the flange 4. with alaterally-disposed flange 6, which constitutes one member of a supportfor the orbitally-movable revoluble elements of the planetary gearing,which connects the motion-transmitting member with the driven member andwhich will hereinafter be described in detail. The pulley 2 is loose onthe sleeve 5 and has a flange 7, which overhangs the flange 6 and isprovided on its inner side with spur-teeth 8, which extend entirelyaround the inner cir- 7o cumference of said overhanging flange.

The motion-transmittingmembercomprises a sleeve 9, loosely mounted onthe drivingshaft 1, and, as shown, it is provided at its inner end witha gear'lO, which is concentrically disposed with relation to the gear 8,formed by the flange of the pulley. This sleeve 9 has at its outer end ahead 9", having an annular friction-flange 9. A head 11 is free torotate on the sleeve 9, as at 12, and is provided on its outer side nearits periphery with outstanding stops 13, of which any suitable numbermay be employed, and the said stops may be disposed at any desireddistance apart. Within the radius of the stops 8 13 are stops 14, whichface in the reverse direction from the stops 13. The head bears againstthe outer side of the pulley 2, and said head, together with the flange6 of the sleeve 5, constitutes a support for the truno nion-shafts of aseries of orbitally-movable revoluble. pinions or planetary gears 15.These gears engage both the gear 10 and the internal gear 8, and therebyconnect the motion-transmitting member with the driven member. Three ofsaid gears 15 are here shown, although a single one will suffice undersome conditions, and any suitable number may be employed within thescope of the appended claims.

The flange 6 of the sleeve 5 is here shown as secured to the head-plate11 by bolts 16,

and together they form a bearing member or support for the pinions 15,and, as before stated, the said support may rotate with the shaft 1 andpulley 2, or it may be locked against rotation. Within the scope of theappended claims any suitable means may be employed to thus lock thebearing member or support of the pinions against rotation. For thepurpose of this specification a looking device is shown which comprisesan arm 17, pivoted at one end thereof to a fixed point, here indicatedas a bearing-plate 18, transversely disposed with reference to the shaft1, and the said arm 17 has guideways 19, in which alongitudinally-movable stop 20 is guided and retained. Said stop may bemoved into position to engage one of the steps 13, and thereby preventrotation of the sleeve 5 and head 11 and prevent the pinions 15 frommoving orbitally, as shown in Fig. 1, to cause the pulley 2 to be drivenin the reverse direction from that in which the shaft 1 rotates. Whenthe stop 20 is disengaged from the stops 13, the pinions 15 are free tomove orbitally with the shaft 1 and pulley 2. The stop 20 has an arm 22,which operates in a slot 23 in one of the guides 19.

At the upper ends of the arms 17 is a fork 17 in which is pivotallymounted a bearing 17*, the pivots of which are shown at 17. The saidbearing comprises a pair of separable sections, retained with theiropposing sides in contact by the fork 17 and the pivots 17, as shown inFig. 3. A longitudinallymovable collar 21 is carried by and rotates inthe said bearing and has flanges 21 and 21 on opposite sides thereof.The flange 21 has stops 21 adapted to engage the stops 14 of the head 11when thecollar is moved toward said head, as shown in Fig. 2. The saidcollar is connected to the sleeve 9 by splines 9 and is hence caused torotate therewith.

The clutch mechanism which communicates motion from the driving memberto the motion-transmitting member or releases said member therefrom ishere shown as a head 26, keyed to the shaft 1 and disposed within theannular flange 9 of the sleeve 9. The said head has radial stops orwings 30, of which there are two formed integral with the head 26in linewith each other. From the outer side of the head projectsaslottedspindle 32, which extends in line with the shaft 1. In the arc-shapedspaces of the head 9 formed between the inner walls of its flange 9 andthe stops 30, projecting radially from the head 26, are radially-movablebrake-shoes 34, which are adapted to frictionally engage the flange 9 ofsaid head 9".

A pair of bell-crank levers 35, having outwardly-extending arms 36, havetheir inner arms 37 pivoted between the bearings 31, formed by the endsof the spindle 32, as at 38, and the ends of said arms 37 aredownturned, forming studs 39,that enter openings in the friction-jaws34, so that said jaws are carried and operated by said bell-cranklevers. The

outer sides of said arms diverge outwardly for a purpose soon to bedescribed. Disposed between the arms 36 is a spring 41, that normallypresses the said arms apart, and thereby draws inwardly the arms 37 andthe friction jaws or shoes 34, engaged thereby, and causes said jaws tobe released from the friction-flange 9.

A cam 42, which is here shown as circular in form, has a central openingto receive the spindle 32, so that said cam may be carried by and isadapted to be moved longitudinally on said spindle, and said cam hasradial notches that communicate with its central opening and in whichthe outer portions of the arms 36 slide. The cam 42 has also an annularperipheral groove 43, adapted to be engaged by a shifting-lever of theusual ,construction for moving the cam longitudinally on the arms 36 tocause the latter to approach or recede from each other. When the cam ismoved outwardly, the bell-crank levers swing on their pivots 38 in suchmanner as to cause the friction-jaws 34 to engage the flange of thefriction-sleeve, and thereby cause said sleeve to rotate with the shaft1 ,as will be understood. Then the pulley is being driven by the shafteither in the same or in the reverse direction, the friction-jaws are inengagement with the flange of the sleeve 9. Prior to changing thedirection of rotation of the pulley the cam 42 must be moved inwardly onthe arms 36 of the bell-crank levers to cause the spring to operate saidlevers, disengage the frictionjaws from the friction-flange, and hencepermit the shaft 1 to rotate in the sleeve 9 independently thereof. Whenthe collar 21 is moved toward the head 11, which may be done by means ofthe arm 17, to engage the stops 21 with the stops 14, as hereinbeforestated and as shown in Fig. 2, and the cam 42 has been moved outwardlyto cause the friction-jaws 34 to engage the flange 9, the pulley 2 willbe driven in the same direction as the shaft 1.

Suitable rods 44 and 45 or other devices may be attached to the upperend of the fork of the arm 17 and to the arm of the stop 20,respectively, to enable them to be operated as may be required from adistant point.

The invention is not limited to the precise construction and combinationof devices hereinbefore described, as it is evident that modificationmay be made therein without departing from the spirit of the inventionas the same is defined by the appended claims.
